50-GR. ACCUTIP (REMINGTON), 200-YARD ZERO

6MM REMINGTON (.243 WINCHESTER)

The 1955 introduction of the .244 Remington paralleled the debut of Winchester’s .243. The .244, based on the .257 Roberts hull (derived in turn from the 7x57), had more capacity than the .243, a necked-down .308 Winchester. But short rifle actions required deep seating of long bullets in the .244, so the ballistic advantages of factory loads were minimal. Remington chambered the round in its M722 bolt rifle. Its 1-in-12 twist proved the correct spin for bullets of 75 to 90 grains. But riflemen wanted heavier bullets for deer and pronghorns. They turned to 100-gr. softpoints in the .243. Winchester’s M70 barrels were rifled 1-in-10. Still, not all tales of twist are true. I owned a Remington 722 in .244 and managed minute-of-angle groups with 100-gr. handloads.
